media: chips-media: wave5: Add support for background detection

Browse source

Implement V4L2_CID_MPEG_VIDEO_BACKGROUND_DETECTION in the Wave5 encoder
driver. When enabled, the hardware detects background regions in a frame
and uses fewer bits or skip mode to encode them, reducing bitrate for
streams with stationary scenes.
